DETAILED DESCRIPTION OF THE INVENTIONReference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the nightlight base of the present invention. For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for illuminating an area and projecting an illuminated display. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.
The present invention is a nightlight that provides illumination and a desired display when energized. Referring toFIGS. 1 and 2, there are shown views of the nightlight display assembly as a whole and a detailed view of thenightlight base30, respectively. The nightlight display is an assembly comprising anightlight base30 and atranslucent plate60 connected thereto. Thenightlight base30 forms an enclosure having anupper surface39 and sidewalls. The sidewalls preferably include alower surface36, arear surface32, and afront surface35. Thetranslucent plate60 is coupled to thenightlight base30 and extends upwardly therefrom. Thetranslucent plate60 preferably comprises a substantiallyplanar surface65 with alower edge69 aligned with alight source50 disposed on thenightlight base30.
Thelight source50 of thenightlight base30 is an upwardly-projecting light that preferably comprises a light emitting diode (LED)55. Thelight source50 projects upwardly and is disposed along theupper surface39 of thenightlight base30. More specifically, thelight source50 may project through atransparent window56 along thenightlight base30, thewindow56 being disposed along theupper surface39 thereof or along the upper surface of a raisedportion51 therealong. In the latter case, theupper surface39 of thenightlight base30 comprises a raisedportion51 forming anelevated surface52 and ashoulder34 between theelevated surface52 and theupper surface39 of thenightlight base30. The raisedportion51 includes upwardly extendingsidewalls53 and a defined cross section that is adapted to be received within asocket80 along thelower edge69 of thetranslucent plate60. Therefore the raisedportion51 is received within thesocket80 to couple theplate60 to thenightlight base30. Thesocket80 includes a recess or aperture therein that accepts the raisedportion51 therethrough. Theplate60 andsocket80 may be coupled together by way of a friction fit joint, or alternatively transparent adhesive may also be applied at the joint to ensure a secure connection therebetween.
Along therear surface32 of thenightlight base30 are electrical outlet prongs31 extending therefrom, which are adapted to couple to an electrical outlet and provide electrical power to thelight source50. Controlling thelight source50 may furthermore be a physical switch provided along a sidewall of thebase30, or alternatively alight sensor40 may be provided. Thelight sensor40 measures ambient light and switches thelight source50 on and off without user interaction. In a preferred embodiment, thelight sensor40 comprises a light-dependent resistor and thesensor40 is disposed along thefront surface35 of thebase30, opposite of theelectrical prongs31. The flow of electrical current from theelectrical prongs31 and to thelight source50 is controlled by an electric circuit within thenightlight base30.
Referring now toFIGS. 1 and 3, there are shown exemplary embodiments of thetranslucent plate60. Thetranslucent plate60 comprises a substantiallyplanar surface65 with alower edge69 aligned with thelight source50 of thenightlight base30. Theplate60 preferably comprisesouter edges61 and a substantially two-dimensional shape; however, three dimensional embodiments are contemplated in which the plate has a varying thickness. The preferred planar shape allows thelight source50 to project light through theedge69 of the plate, wherebyindicia62 along theplate60 reflects the light to highlight theindicia pattern67 thereon. Theindicia62 reflects the light in a preferably diffuse pattern, however specular reflection of the light from theindicia62 is also contemplated.
The material of thetranslucent plate60 is preferably a thermoplastic material, such as acrylic glass or the like. Acrylic glass is a transparent thermoplastic material that can act as a background for theindicia pattern67, which reflects the incoming light from thelight source50 while theplate60 serves as a clear or colored background therearound. Therefore, theplate60 may comprise a translucent or transparent plate, while theindicia62 thereon is substantially opaque thereon and disposed in a manner to reflect incoming light as the light travels through the plate thickness from itslower edge69.
Theindicia62 on theplate60 may be created in several different manners. In a preferred embodiment, theindicia pattern67 is etched along the surface of theplate60. Theindicia pattern67 is formed through a laser etching or alternative etching process, thereby creating apattern67 on theplate60 that reflects the edge light. Alternatively, theindicia pattern67 further comprises engraved indicia, printed indicia, or silkscreened indicia on the plate surface. Engraved indicia are created through a cutting process in which material from the surface of the plate is removed or roughened to create the desired pattern. When light reaches the engraved portions, the light scatters or is otherwise reflected through the rough surface thereof. Likewise, printed orsilkscreened indicia patterns67 are paint or material deposited onto the surface of theplate60, wherein the material reflects the edge light when the light is energized. Since the plate is translucent or transparent, the display pattern will be illuminated in dark light using any of these processes. Therefore, the nightlight projects light upward while illuminating a specific pattern defined by theindicia62.
In some embodiments, theplate60 is removable from the nightlight base to allow the user to change the display. As shown inFIG. 3, theplate60 may comprise asocket80 along itslower edge69. Thesocket80 includes arecess82 defined withinsocket walls81 and a socketupper surface83. The raisedportion51 of the nightlight base is received within therecess82 of thesocket80, connecting the two together. The connection may simply be a friction fit or press fit between thesocket80 and raisedportion51, or alternatively optical adhesive may be applied at this joint to maintain the connection.
In addition, theplate60 may be removably connected to the raisedportion51 via a sliding joint, as provided inFIG. 5. As shown, in this embodiment the sidewall of the raisedportion51 forms achannel54 that is adapted to receive thelower edge88 of thedisplay socket80. More specifically, the raisedportion51 of thehousing30 has a groove orchannel54 that extends inward from its sidewalls. Thedisplay socket80 also has alower edge88 that extends inward from thesidewalls89 of thesocket80. Thislower edge88 forms a perimeter that is adapted to be received and abutted against theinner surface58 of thechannel54, wherebysocket80 slidably engages thechannel54 of the raisedportion51 to secure the same. One end of thesocket80 is open, and the upper end of the raisedportion51 is received within therecess82 of thesocket80 when the two are slidably engaged. This prevents the display from be separated from the housing via upward tension. Rather, thelower edge88 engages thechannel54 in friction/press fit, and are removable when pressed apart in a lateral direction (i.e. towards the closed end of the display socket80).
Referring now toFIG. 2, there is shown a view of an embodiment of thelight source50, whereby the light55 is disposed below atransparent window56. In this embodiment, thetransparent window56 is positioned over the light55 and may comprise a colored surface that changes the color of the light projected from thenightlight base30 and into the plate. This embodiment may be used to project a display of certain color. Alternatively, thetransparent window56 may be clear and the light55 itself may be a colored LED. In either embodiment, the plate and the indicia thereon will project the color of the window or LED color.
Referring now toFIG. 4, there is shown an embodiment of theelectrical circuit100 within the nightlight base. Theelectrical circuit100 comprises alight emitting diode55 and supporting electrical components to emit light from the nightlight base and control the flow of current from theelectrical prongs31 and flowing through thecircuit100. In the embodiment shown, the LED circuit includes anLED55, one or more transistors41, aresister R342, and a light-dependent resistor40. The light-dependent resistor40 and transistor41 control the flow of current to theLED55, whereby low ambient light triggers the circuit to activate theLED55. Alternatively, a physical switch may be provided for the user to manually activate the LED. In addition, theelectrical circuit100 comprises an R1-R2-C2 circuit45 and a ZD1-ZD1-C1 circuit48. The R1-R2-C2 circuit functions by providing an AC impedance that limits the AC current in the circuit. The ZD1-ZD1-C1 circuit functions as a half wave rectifier to produce a constant DC voltage to power theLED55. This specificelectrical circuit100 is one embodiment contemplated by the present invention.
Overall, the present invention provides a new nightlight device with a nightlight base and a nightlight display. The display is formed by the upwardly projecting light source and the edge-lit plate, which includes indicia thereon that reflects light in the pattern of the indicia. This provides ambient light and displays a specific symbol, display, message, or other pattern from the plate. The size of the plate and the shape of the plate perimeter may vary in order to provide user customization. In addition, the indicia thereon may form a specific display, as desired by the user.
